ODL stands for Open and Distance Learning, which is a way of providing distance education opportunities that seek to mitigate or remove barriers to access, such as finances, prior learning, age, social, work or family commitments, disability, incarceration or other such barriers. The term "open" refers to a commitment that removes any unnecessary barriers to access learning, while "distance education" refers to teaching and learning that temporarily separates teacher and learner in time and/or place.

ODL can also refer to other things, such as:

• ODL Inc.: A company that makes door glass and door blinds for entry doors.
• Ripple on-demand liquidity (ODL): A product that helps customers move money around the world without the need for correspondent banking relationships and the pre-funding of accounts abroad.
• Occupational Drivers License (ODL): A type of restricted drivers license that can be issued to individuals who have had their regular drivers license suspended or revoked, usually for reasons such as unpaid traffic fines, failure to maintain auto insurance, or a criminal conviction.
• Online Distance Learning (ODL): A way of learning remotely without being in regular face-to-face contact with instructors/lecturers and other students.

In summary, ODL can refer to a variety of things, but it generally refers to a way of providing distance education opportunities that seek to remove barriers to access.
